basic question on Rubi 4.2 output from Int[] command

Using Rub 4.2:
 ShowSteps = False; int = ((2^(x)  3^(x))/x)^a; Assuming[Element[a, Integers] && a > 0, Int[int, x]] 
(((2^(x)  3^(x))/x)^a*x^a* Int[(2^(x)  3^(x))^a/x^a, x])/(2^(x)  3^(x))^a
My question, Am I reading this right: I see the integrand printed again, but it is outside the integration again. So it did not do the integration (neither did Mathematica) but why then I see the integrand printed again outside the integral?
thanks, Nasser
